Embodiment Construction
[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0029] see Figures 1 to 3 As shown, according to the embodiment of the present invention, a method for sewing bladder materials is provided. The bladder 100 of this embodiment is a buoyancy-providing bladder applied to an aerostat in an adjacent space, and includes a plurality of sequentially docked bladders The petals 14 , the sequentially butted capsule petals 14 form a spherical shape as a whole, and a butt line 142 is formed between adjacent capsule petals 14 . After the capsule 100 enters the adjacent space, its diameter ranges from 10-50 meters, preferably 20-45 meters. It can be understood that the shape of the capsule 100 in this embodiment may also be pumpkin-shaped or drop-shaped o...

The invention provides a capsule material, a method for sewing the same and an aerostat. The method for sewing the capsule material includes steps of covering a first side of each butted gap of each two butted capsule base material layers and sewing each first reinforcement bearing layer; covering a second side of each butted gap and sewing each second reinforcement bearing layer; respectively arranging protection layers on the certain surfaces of each first reinforcement bearing layer and each second reinforcement bearing layer. The second side of each butted gap is opposite to the first side of the butted gap. The certain surfaces of each first reinforcement bearing layer and each second reinforcement bearing layer are far away from the corresponding capsule base material layers. The capsule material, the method and the aerostat have the advantages that structures of the capsule material sewn by the aid of the method are symmetrical with one another on the first sides and the second sides of the butted gaps, a part of concentration of stress generated by the first reinforcement bearing layers on the first sides of the butted gaps can be offset by a part of concentration of stress generated by the second reinforcement bearing layers on the second sides of the butted gaps when the capsule material is used, accordingly, peeling stress of the integral capsule material can be reduced, influence of the peeling stress can be effectively reduced, and the strength of joints of the capsule material can be improved.
Description
technical field [0001] The invention relates to the field of aviation technology, in particular to a method for sewing a capsule material, a capsule material and an aerostat. Background technique [0002] An aerostat refers to an aircraft whose specific gravity is lighter than air and relies on atmospheric buoyancy to lift into the air. With the development of aerostats in adjacent space, higher requirements are put forward for the main material of aerostats - the capsule material. Capsule material The material is generally composed of a capsule base material layer, an airtight layer, and a protective layer. The capsule material is required to have the characteristics of high strength, high air tightness, and low weight. The airbag of the aerostat is generally sutured by the capsule flap. [0003] The capsule material should meet the flight requirements of the near space environment. The atmosphere in the adjacent space is thin, the ultraviolet light is strong, the temper...
